There are many causes of heart failure.
|
 |
And, there are many ways to look at heart
failure. |
 |
Systolic failure and its causes. |
 |
Systolic failure can be segmental (left
with thrombus) or global (right). |
 |
Coronary artery disease must be excluded
every time there is systolic failure. |
 |
As we saw in the pathologic segment,
infarction can remodel the left ventricle. |
 |
Echo can measure many things. All may
be useful, but it is impossible to do all. |
 |
Even more can be measured to assess systolic
failure. |
 |
Overall ejection fraction is most common. |
 |
EF indicates prognostic information. |
 |
Echo in Context |
 |
Most big trials indicate that treatment
with ACE Inhibition help outcome. |
 |
Stress echo has a role in detecting ischemia
as the cause, particularly silent ischemia. |
 |
Viability by stress methods help determine
prognosis. |
 |
Like everything, there are limitations
to measurement. |
 |
Contrast may help to overcome poor visualization
of borders. |
 |
Regional, or segmental changes can also
be assessed. |
 |
And, of course, we can score the walls
movement. |
 |
Wall scores are useful for prognostic
information. |
 |
Color wall tracking can help with segmental
wall abnormalities. |
 |
Doppler tissue imaging can help also
by showing velocity of walls, not just direction of motion. |
 |
This is the concept of remodeling. |
 |
The recent Guidelines stress the use
of echocardiography. |
